1 b all whom it may concern:

.Be it knownthat l, SIMEON C. LaWLoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Container-Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others Skilled in the art to which it appertain's to make and use the same.

This invention relates to improvements in sustaining or supporting elements for co'ntainers, such as scrubbingpails and other vessels.

One of the objects in view is the provision of a shift-able support having means for detachably clamping or gripping a container and retainingthe same in operative relation to the support.

lVith this and other objects in view as Will in part hereinafter become apparent and in part be stated,the invention comprises certain novel constructions, combinations and arrangements of parts as will now be specilied and subsequently pointed out in the appended claims.

In the accompanying drawing:

Fig. 10 is a view 111 front elevation of the part seen in Fig. 9, the upper portlon 0f the clamp being broken away and the container being omitted.

Figs. 2 and 3 are cross sections onlines 2", 2 and3, 3 of Fig. 2.

Referring to the drawing by numerals, 1 indicates a support made up preferably of strips of material crossed and secured together in any appropriate manner as by a rivet 2 at the point of crossing. The strips making up the support 1 are preferably of heavy gage strap iron or other like appro priate material. Thestrips which form the support 1 in their radiation from a common center may be considered arms, and fixed to the support at the common center, as by being engaged by the rivet 2, is an additional arm 3 which is also preferably formed of a strip of material such as heavy gage strap iron; The arn'r 3 outstands radially from the central point approximately inidwaybe tween two of the arms of support 1, and at its outer end portion is surrouiuled by a slidingly mounted sleeve 4, said sleeve being provided with a pin or rivet 5 extending through a slot 6 formed in the arm 3 so as to guide the sleeve 4: in its longitudinal movement. A spring 6 is fixed to the inner end portion of arm 3 and engages sleeve 4, by being connect-ed to the pin 5, so as to exert pressure on" the sleeve tending to move the sleeve inwardly. The lower outer end portion of the sleeve 1 is bent downward to form a handheld or hookshaped grip 7 and the upper outer end portion of the sleeve is bent to form an up standing stop 8, which stop is curved to form a bead receiving corrugation 9. Obviouslyany shaping of the upturned portion 8 which produces a groove adapted to receive the bead of a bucket or other eontainer, for instance as seen in Fig. 1, may be employed in lieuof the corrugation 5). Two of the arms formed of the strips making up support 1 terminate at 10, 10, and these two arms are those which with the arm 3 form a Y-shaped frame. Each of the arms terminating at 10 has its end portion inclosed by a slidingly adjustably mounted sleeve 11. A guiding pin 12 engages the terminal portion of each of the last named arms, and extends through a slot 13 in its respective sleeve 11. The pin 12, while shown in the form substantially as a rivet may be constructed in any desired manner, as for example, from the material of the respective arm struck up through the slot 13. A. clamping bolt 14 extends through the slot 13 at each sleeve 11, and through the respective arm and is provided with a wing nut 15 adapted to be threaded along the belt for enabling adjustment of the sleeve 11 and for clamping the sleeve in its adjustable position. The outer end portion 01 each sleeve 11 is upturned to form a stop 16 similar in structure and function to the stop 8 and provided with a bead receiving corrugation or grooved portion 9 similar in form and function to the part 9. A plate 17 is fixed to the outer portion of each sleeve 11 as by being riveted or otherwise appropriately connected thereto and each plate 1'? is supported by adownwardly extending floorengaging member, preferably in the term of acaster 18 which may be of the ordinary conventional type. support 1 opposite those engaged by slides or sleeves 11 is engaged by a slide or sleeve 19 and has a pin and slot connection there with, the slot being preferably formed in the respective arm as at 20, and the pin consisting of a bolt or other similar part 21, extending through the slot and through the sleeve 19 and engaged by a nut beneath the sleeve so as to be adapted for clmnping the sleeve 19 at any given adjustment longitudinally of the respective arm. Extending downwardly from the outer terminal por tion of each slide or sleeve 19 is a floor en'- gaging element consisting preferably of the ordinary conventional caster 22.

The operation of the structure should be apparent and may be briefly stated to con sist of sustaining a. scrubbing bucket or other like receptacle by having the bottom of the bucket fitted between the steps 8 and 16, and clamped thereby under the pressure of spring 6. The ordinary scrubbing pail is provided with an annular bead at its base which is engaged by the grooved portions 9 and 9, which efi ectively locks the bucket to the base 1 and prevents accidental dislodgment. The supportl is thus a coaster for the sustained receptacle and greatly facilitates shifting of the same about the floor.

Ordinarily, the stops 8 and 16 are suflicient for preventing dislocation of the supported receptacle but as a further precaution against relative movement of the bucket with respect to the support, there are provided clamping apparatus designed to engage the upper edge of the receptacle and to clamp the same down against the support. Each of such clamping apparatus consists of a connecting rod 23 having a hook 23 at its upper end designed to engage the upper edge of the receptacle. The lower end of rod 23 is provided with a pair of eyes, each engaged by a coil spring 24h: each 01 which spring structures depends from the rod 23 and is provided at its lower Each of the arms of end with a hook 25 designed to engage an eye in the respective stops 3 and 16. As two springs 24 are employed, each of said stops is preferably provided with two eyes.

111 Figs. a and 5 is illustrated a slightly modified form of connection between the supporting caster and the arms formin the main support. 1, 1 are the arms oi said support with the additional arm 3 fixed together by the central rivet 2. In lieu of the forms of connections of the casters to the arms just above described a caster 18 is pivotally connected to a plate 17" which is inclosed by a sleeve 19 also surroundingthe outer portion of the respective arm 1. The sleeve 19 and arm 1 are provided with registering longitudinal slots 2.0 through which extends a bolt 21, said bolt also extending through an aperture in a plate 17, and its lower end portion being engaged by a wing nut 21. The sleeve 19" is open, are all of thesleeves above described, and the nut 21 seats directly against plate 1", so that by tightening up'the nut, plates 17 and the arm 1 can be clamped together and the caster thus locked to the support memher in any given adjusted position. The outer terminus of the sleeve 19 is formed with an upturned stop portion 16. which is identical in form and function with stop 16.

The structure seen in Figs. 6, 7 and 8 differs from that seen in Fig. 1, chiefly inthe fact that the arms forming the support have their outer ends connected by a still enin ring.

With this in mind and referring particularly to Figs. 6, 'T and 8, the structure therein seen will be observed to consist of a support formed of radial arms 31, 31, 32, 32, and an interposedarm 33, and connected centrally by a rivet 3st. The outer end portion of each 01 said arms is bent upwardly at 35 1 ing a ring 37. Ring 37 may be of any appropriate materlal, but is preferably a metallic rod, and is designed particularly to prevent any dislocation of the arms relative to each other. The arms 32 are engaged by sleeves 38, each having a stop39, and each being formed with a longitudinal slot so, through which a bolt a1 ispassed, which bolt 11 extends through the respective arm 32, engaged by sleeve 38 and a nut 42 is threaded on to the respective bolt 11 beneath the arm so as to enable clamping of the sleeve 38 at any desired point of ad ustment. The sleeve 38 is open underneath the engaged arm, and in fact, may be constructed in the form of a simple sliding plate. The outer portion of each arm 32 is engaged and sustained by a caster 13, and the outer portion of each of the arms 31 is similarly engaged by a similar caster 4:3. The arm 33 is engaged by a sleeve 4A having a pin and slot connection with the arm 33,

and formed into an eye 36, surround Laeaeoe and being engaged'by a spring 45, connected to the IDHGPPOIUOII of the arm and tensioned to draw thesleeve or slide 44 inward. The outer end of the slide or sleeve 44 is provided with an upstanding stop 39, the several stops 39 and'39 being the same in structure and function as the stops 16 and 8. Depending from the sleeve 44 is a curved grip-or-handle46, adapted to be grasped by the operator for drawing the sleeve 44 out. ward against the tension of spring 45, when a receptacle is to be introduced between the stops 39, 39, and 39'] In practice, a receptacle is positioned merely by drawing the sleeve 44 outward and placing the re ceptacle upon the supporting arms 31 and 32, with the head of the receptacle engaging the groove of the stops 39, the slide 44 having been drawn outward enough to clear thercceptacle, and after it has been positioned in engagement with the stops 39, the sleeve 44 is released and the stop 39 thus caused to engage the receptacle under the tension of spring 45. It is obvious that this is the same operation asthat employed in applying the receptacle to the structures seen in Figs. 1 and 2. Receptacle retaining stays may be employed in this construction identical with those seen in Fig. 1, each consisting of the rod 23 and springs 24 and their connected parts. Preferably these stays in this construction are arranged with one of the springs in engagement with one of the respective stops and with the other spring in engagement with the ring 37.

In Figs. 9 and 10, I have shown a further modification, in which the major portion of all of the arms is eliminated and only a short section of plate 51 is employed for each caster '52. Upon each plate 51 is fixed a plate 53, having an upstanding portion 54, the plates 51 and 54 being formed with bent portions 55 and 56, respectively, for forming a bead receiving groove for the receptacle. Fixed to the upstanding portion 54 is a sleeve 57, through which extends a stay rod 58, having a hook 59 at its upper end adapted to engage the upper end of the receptacle. The lower end of stay 58 is engaged by an adjusting nut 60, and a coil spring 61 is interposed between the nut 60 and the sleeve 57 and tensioned to pull downwardly on the rod 58 for producing a clasping or gripping action by the hook 59 in coiiperation with the parts 55 and 56. As many of the supporting elements 51 and connecting parts are provided for a bucket as preferred, three being sutficient, but four being preferably used and a greater number may be supplied where the receptacle. is relatively large.
